Abstract:

On the Starkey Experimental Forest in northeastern Oregon pileated woodpeckers (Dryocopus pileatus) nested in dead ponderosa pine (Pinus ponderosa) (73%), dead western larch (Larix occidentalis) (25%), or live grand fir (Abies grandis (2%). The diameter at breast height (dbh) of 105 nest trees averaged 84 cm, and nest height averaged 15 m. Fifty-five percent of nest trees had broken-off tops. At 67% of the nest sites the surrounding stand was Grand Fir Forest Type. Trees used for roosting were similar to nest trees but had been dead longer. Juveniles dispersed an average of 3.4 km from where they were raised to where they later nested.
